Interesting feature/bug with raid window

[Siebzhen]

ok i updated drumsui around 5pm cst today useing the auto updater.

and i noticed something was different about my raid window.

Any time i had someone in the raidwindow moused over and hit my enter key the #1 skill in the 5x click to use ability would cast on my mouse over target.

is this a bug?

if it is... this is so so very close to a requested feature people have been asking for called hovercast.

Is there a way to rebind it so instead of hitting enter i would just press 1 on my keyboard?

Is there a way to make it so it does the same with my other x5 clicks as well?
